Fan Tray
The device provides a Fan Tray module, located on the front panel, which is concealed by a fan
tray cover. The Fan Tray module contains six individual fans which cool the device's internal
components to maintain an acceptable operating temperature inside the chassis.
The Fan Tray module draws air in from the outside through the perforated fan tray cover on
the front panel (see following figure). A replaceable air filter, located inside the fan tray cover,
removes dust particles from the sucked in air. The incoming air passes through the chassis,
cooling the internal components and then exits the chassis through the vents on the rear
panel (see following figure).
Figure 3-2: Airflow Directions through Chassis
When installing the chassis, make sure there is sufficient front- and rear-side clearance
for proper airflow into and out of the chassis.
Figure 3-3: Fan Tray Module

CHAPTER3 Physical Description MP-1288 | Hardware Installation Manual
Figure 3-4: Fan Tray Cover
The Fan Tray provides a LED indicating the operating status of the Fan Tray module. For more
information, see FAN LED on page5.
During system operation, the inner ambient temperature is continuously monitored. Upon
excessive temperature conditions, an SNMP Temperature Alarm is generated
(acBoardTemperatureAlarm). Upon a speed degradation or full stop of any fan, an SNMP Fan
Alarm (acFanTrayAlarm) is generated.
The Fan Tray module is hot-swappable, allowing you to replace it even when the device is
powered on. The Fan Tray module, fan tray cover, and air filter are available as field-
replaceable units (FRU). For replacing the Fan Tray module, see Replacing the Fan Tray Module
on page39. For replacing the air filter, see Replacing the Air Filter on page41.
For replacing the Fan Tray module or any of its components, perform only the
instructions as described in Replacing the Fan Tray Module on page39.
Rear Panel Description
The device's rear panel is shown in the following figure and described in the subsequent table.

The figure above is used only as an example. The number of installed FXS blades, and number
and type of Power Supply modules (AC or DC) depend on your ordered hardware
configuration.

FXS Blades
The FXS blade (referred to as Module in the device's management interfaces) provides the FXS
port interfaces. Each blade provides three FXS port connectors - 50-pin Telco connector
(Centronics type). Each connector provides 24 FXS interfaces and therefore, each blade
provides up to 72 FXS interfaces (3 x 24 FXS). The device can be housed with up to four FXS
blades thereby, supporting up to 288 FXS port interfaces (4 blades x 72 FXS). The FXS blades are
available as spare parts. For replacing FXS blades, see Replacing the Fan Tray Module on
page39.
Each FXS blade provides a LED on the front and rear panel, as described in FXS LEDs on
page14.

Power Supply Module
The device can be powered from an AC or a DC power source. The type of power depends on
your ordered hardware configuration.
AC Power Supply Module
For the AC- powered model, the device provides two AC Power Supply modules for load
sharing and power redundancy. The power source is a standard electrical outlet providing AC
power.
Power surge protection, caused for example from lightning, is also supported. For more
information, see Grounding and Surge Protection on page19.
The Power Supply module is available as a spare part. The Power Supply modules are hot-
swappable and therefore, if only one needs to be replaced, it can be done while the device is
receiving power from the working Power Supply module. For replacing Power Supply modules,
see on page50.
